Why No Two Sites Agree on Corte Madera's Median Home Price

Pull up four real estate sites in the same afternoon and ask what a home costs in Corte Madera right now. You will get four different answers, and none of the people who published them are wrong. They are all describing the same nine-thousand-person town, often in the same calendar year, and the numbers still refuse to line up.

Here is what a spot check of 2026 data actually looks like when you set the figures side by side:

That is a spread from $1.14 million to $2.51 million, drawn from the same town in the same twelve-month window. If you are shopping Corte Madera against Larkspur, Mill Valley, or San Rafael and treating any one of these numbers as the town's price, you are comparing your budget to noise.

The town barely trades

The mechanism here is not mysterious once you see the sales counts. A median needs enough transactions to mean something, and Corte Madera does not generate many. The Redfin figure above was built from 8 closed sales. The March 2026 comparison was built from 6. A separate check of neighboring Larkspur in February 2026 found only 4 sales behind that town's headline number.

When a monthly median comes from single digits, one buyer's decision to pay $50,000 over ask on a hillside estate, or one seller's decision to list a dated ranch below market to move fast, can shift the reported town average by a meaningful percentage. That is not a market correction. That is arithmetic behaving exactly as it should with a small sample. A statistician would call this normal. A buyer scrolling between four listing sites in one sitting just calls it confusing.

One house can move the whole chart

Look at what was actually for sale in Corte Madera in a single week this spring: a two-bedroom home listed at $545,000 in the same town, the same month, as a $2.45 million three-bedroom, three-bath home on a small lot. Zoom out further and the full range of homes listed across the town that spring ran from roughly $366,000 up to $8.5 million.

That range exists because Corte Madera is not one housing market wearing one price tag. It is a handful of small, distinct pockets, and whichever pocket happens to trade in a given month decides what the headline number says. A month that closes two condo sales and one hillside estate will report a wildly different median than a month that closes five ranch homes on the flats. Neither month is describing a rising or falling market. Both are describing whoever happened to sell.

The number that actually matters is the neighborhood, not the town

If the citywide median cannot be trusted, the fix is not a better citywide number. It is skipping the citywide number and looking at what a given pocket of Corte Madera has actually done.

A few of the town's distinct micro-markets, and what tends to separate them:

• Christmas Tree Hill. One of the oldest sections of town, with around 250 dwelling units on narrow winding roads and stairs above the historic Old Town Square at Menke Park. Homes date from the early 1900s through the 1960s, many with sweeping bay views, and inventory here is naturally scarce simply because there are so few homes to begin with.
• Madera Gardens, also known locally as Lakeside. Wide, level streets of ranch homes built through the 1950s and 60s on filled marshland, organized around three town-maintained lagoons. Many homes have private docks, and west-facing lots pick up Mount Tamalpais views.
• Chapman Park, including the Pleasant Valley sub-area. Starts flat along Tamalpais Drive and climbs toward Camino Alto, mixing smaller California cottages with larger hillside homes. Pleasant Valley, near the top of Sausalito Street, trades on privacy and view more than square footage.
• Meadowcreek Station and Madera del Presidio. Built between 1988 and 1994, together totaling around 300 homes at the edge of Ring Mountain, this pocket is where the town's condos and townhomes concentrate, and it consistently anchors the lower end of Corte Madera's price range.
• The bayside flats, including Mariner Cove. Newer construction, flat terrain, wider streets, and closer proximity to the Larkspur Ferry Terminal, the Richmond-San Rafael Bridge, and Ring Mountain Nature Preserve.

Ask what a Christmas Tree Hill view home sold for last quarter and you get a real answer, because you have controlled for the variables that actually drive price: lot type, age of construction, and view corridor. Ask what "Corte Madera" sold for last quarter and you get an average of a hillside Victorian, a lagoon ranch, and a 1990s townhome, none of which compete with each other for the same buyer.

The same problem shows up anywhere towns get compared

This is not unique to Corte Madera. A March 2026 comparison of Corte Madera and Larkspur found nearly identical median sale prices, $2.51 million and $2.618 million respectively, both drawn from single-digit sales counts (6 and 5 homes) in the same month. Both towns sold above list that month, Larkspur at 113.2% and Corte Madera at 104.1%, and both figures are equally fragile. A buyer reading only the headline could conclude Larkspur runs meaningfully more expensive. A buyer who checked the sample size would conclude the two towns were statistically indistinguishable that month.

The lesson carries across every small-town comparison in this part of Marin. Whenever a market this size gets compared to its neighbor, the difference in the headline is often smaller than the noise in the sample.

What to actually do with any median you see

Treat any single-month, town-wide figure as a data point, not a verdict. Before you let it change how you think about a market:

Ask how many homes closed behind the number. Single digits mean the figure can swing on one sale.

Check the date stamp, not just the label. A page that says "last month" is not always describing last month. Some of the data cited above was labeled that way while actually reflecting a close from over a year earlier.

Ask for closed comps within your target pocket over a six to twelve month window, not the whole town over thirty days. A lagoon-front ranch in Madera Gardens and a condo in Meadowcreek Station were never competing for the same buyer, and averaging them together tells you nothing about either.

Frequently asked questions

Why do Zillow and Redfin show different numbers for the same town? They are measuring different things. Zillow's Home Value Index is a smoothed estimate across all homes, whether they sold or not. Redfin's monthly median reflects only the handful of homes that actually closed that month, which is why it moves so much more sharply.

Does a lower median list price mean the market is cooling? Not on its own. A lower monthly median can simply mean smaller or older homes happened to list that month. Days on market and sale-to-list price ratio, tracked over several months, tell you more about direction than a single median.

Is Corte Madera cheaper than Larkspur? Depending on the month you check, the headline numbers have shown Corte Madera anywhere from meaningfully below Larkspur to nearly even with it. Given how thin both markets trade, the honest answer is that the two towns are close enough that lifestyle fit, commute, and housing type should decide the comparison, not a monthly median.

If you are trying to make sense of what a specific pocket of Corte Madera, or a specific home type, has actually done over the past year, that is a conversation best had with someone tracking closed comps street by street, not a portal refreshing a citywide average.
